BES update sp6 with OCS
 

So the latest BES update enables OCS connectivity on the BB's but it says it's only a "test" so we didn't enable it on a production BES.. well.. we decided to go for it and try it

do I have to fully reinstall sp6? or can I download just the OCS components somewhere?

On your production BES (or whatever BES you want to use for Collaboration Services) just run the SP6 installer and make sure you choose BlackBerry Collaboration Services as part of the installation.
This is what is needed to connect to OCS 2007.

Yeah.. we've already installed Sp6 and unchecked the OCS features.. Can I reinstall Sp6 and select ONLY the OCS features? or is there a standalone that allows those features to be installed?

Just run the installer again and install collaboration services.
